一、概念----是做什么的能干什么

   Fancytree是一个Javascript控件,它依赖于:

    <script src="jquery.js"></script>
<script src="jquery-ui.min.js"></script>
<link href="ui.fancytree.min.css" rel="stylesheet" />
<script src="jquery.fancytree-all.min.js"></script>

   具有以下几个亮点功能:

1)   支持Tree Table

2)   checkbox选择框有三种状态,并可以disable掉checkbox选择框

3)   丰富的示例展示和代码展示、详尽的介绍文档、丰富的事件支持

  4)   节点可编辑、拖拽、过滤、全选、统计子节点、延迟加载、皮肤设置、事件钩子支持、右键菜单、树内部可加入多种控件。

二、入门步骤

    1)最简陋、基本的树

    2)Fancytree所有配置项—名称、类型 的介绍

    3)Fancytree的事件的大体使用介绍

    4)Fancytree的属性、方法、参数的使用介绍

    5)FancytreeNode 的属性、方法、参数的使用介绍

    6)JS调取Fancytree、FancytreeNode对象和属性

    7)Fancytree的事件钩子使用

    1)  
最简陋的树

    

    

      <head>

      <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

       <title>fancyTreeTest</title>

      <script src="jquery.js"></script>

      <script src="jquery-ui.min.js"></script>

       <link href="ui.fancytree.min.css" rel="stylesheet" />

      <script src="jquery.fancytree-all.min.js"></script>

       <script type="text/javascript">

      $(function () {

      //Create the tree inside the <div id="tree"> element.与zTree类似

       // 基础配置,返回数据包括

       $("#tree")

       .fancytree({

       source: [

        { "title": "Node 1", "key": "1" },

        {

       "title": "Folder 2",

         "key": "2",

            "folder": true,

              "children": [

              { "title": "Node 2.1", "key": "3" },

        { "title": "Node 2.2", "key": "4" }

        ]

           }

        ]

         });

       });

      </script>

      </head>

      <body>

      [...]

      <!--  show tree  -->

      <div id="tree">...</div>

       [...]

      </body>

      运行结果为

      

    如果将以上的 body换为

      <body>

      [...]

      <!--  show tree  -->

      <table id="tree">...</table>

      [...]

    </body>

    运行结果为

    

    最简单的树就完成了。

(node.setTitle(), moveTo(), addChildren(), remove(), ...) already handle
this.

Rename this node.

Details

void

Return false if iteration was stopped.

Details

$.Promise

visitAndLoad(fn, includeSelf=false)

Call fn(node) for all child nodes and
recursively load lazy children.

bottom-up, including invisible system root.
Stop iteration, if fn() returns false.

        //获取Id为tree的Fancytree对象
        $("#tree").fancytree("getTree")         //获取tree的根节点
        $("#tree").fancytree("getRootNode")         //访问每个节点并把节点展开
        $("#tree").fancytree("getRootNode").visit(function(node) {
node.setExpanded(true);
